FOREWORD The Oil Industry in India is more than 100 years old. Because of

various collaboration agreements, a variety of international codes, standards and practices have been in vogue. Standardisation in design philosophies and operation and maintenance practices at a national level was hardly in existence. This coupled with feed back from some serious accidents that occurred in the recent past in India and abroad, emphasised the need for the industry to review the existing state- of- the-art in designing, operating and maintaining oil and gas installations.

With this in view, the Ministry of Petroleum and Natural Gas in 1986

constituted a Safety Council assisted by the Oil Industry Safety Directorate (OISD) staffed from within the industry in formulating and implementing a series of self regulatory measures aimed at removing obsolescence, standardising and upgrading the existing standards to ensure safe operations. Accordingly, OISD constituted a number of functional committees of experts nominated from the industry to draw up standards and guidelines on various subjects.

The present standard on “Guidelines for Replacement of Life Saving and Personal Protective Safety Items (STD-184)” was prepared by the functional committee based on industry experience and on various national and international standards and codes of practice. It is meant to serve as a users guide and is no way, a substitute for existing standards and manufacturers recommendations. It is hoped that the provision of this document, if implemented objectively will go a long way in improving the safety standard of oil and gas industry. This document will be reviewed periodically for improvements based on the new experiences and better understanding. Suggestions from industry members may be addressed to : -

1.0 INTRODUCTION

The life saving appliances are the means which are used during emergency, to ensure emergency preparedness. These appliances are the life boat, survival craft and scrambling net etc. Similarly the personal protective equipment (PPE) are primarily required for the personal protection and these are the secondary means of protection, the primary protection being the engineering controls. It is, therefore, necessary that certain minimum standard regarding the specifications are maintained in order to ensure quality and also to standardise its replacement norms which is based on the normal usage pattern.

It is noted that disparity exists amongst different organisations as regards the PPE specifications and also the PPE replacement norms. The disparity regarding the specifications and replacement norms exists within the same organisation also at different functional units. The same situation exists for the life saving appliances as well. Accordingly, a need was felt among the industry members for the guidelines to be prepared regarding the specification and replacement norms of life saving appliances and the personal protective equipment, due to the following reasons:

1. To ensure quality through standardised

specifications 2. To provide industry guidelines to

facilitate procurement of quality items 3. To suggest replacement period / norm 4. To establish uniformity in the industry as

regards the provisioning, issuance, replacement of life saving and as well as PPE items.

To facilitate provisioning, usage and the replacement, it is equally important to understand the qualitative features of the life saving appliances and also the personal protective equipment. Accordingly, to facilitate understand the broad features of the personal protective equipment items, its

qualitative features have been provided. Similarly, the description and the qualitative features of the life saving appliances have also been covered to a large extent.

4.0 PERSONALPROTECTIVE

EQUIPMENT: 4.1 GENERAL INFORMATION; 4.1.1 Torso and body protection Proper clothing should be provided to all personnel working at operational sites. Only cotton overall (dangri) should be worn by the personnel working in the fields. Wind cheaters and rains coats should also be used in extreme weather conditions. 4.1.2 Eye and Face Protection Eye and face protection should be provided in hazardous environment where there is a reasonable probability that related injuries can be prevented or reduced by the use of such equipment. Suitable eye protection should be used where machines or operations present danger from flying objects, flash lights & glares and hazardous liquids injurious radiation or a combination of these hazards. Protectors should meet the following minimum requirements: 1. It should provide adequate protection

against the particular hazard for which they are being used.

2. It should be reasonably comfortable when worn under the designated conditions.

4

3. It should fit snugly and should not unduly interfere with the movement of the wearer.

4. It should be durable. 5. It should be capable of being disinfected

and cleaned (unless they are disposable.)

Goggles, Face masks, Face shields, Side shields, Safety glasses, Welder’s lens etc. are used for protection of the eyes. These are required for welding, grinding, gas cutting and while handling corrosive chemicals. Personnel using these eye protectors should undergo examination for visual acuity and depth perception. 4.1.3 Head Protection Head protection should be used where there is a danger form impact or penetration from falling or flying objects or from limited electric shock or burn. The head protectors should be of comfortable and proper fit. Helmets, Hard hats, Safety hats (full brim, brimless, limited voltage protection, no voltage protection) etc. are used for head protection. Thin-shelled plastic “bump caps” should not be used as a substitute for approved head protection. 4.1.4 Foot Protection Foot protection should be provided where there is a potential for foot, toe or instep injuries from external forces. Safety shoes, Gum boots etc. are used for foot protection. A toe box, cup or instep protector may be incorporated as an internal part of footwear during construction or a variety of suitable approved foot guards to cover or attach to standard work shoes may be utilised. Additionally, the footwear should have a sole on insole that will protect against penetration. 4.1.5 Hand Protection Hard protection should be used where there is danger of cuts such as handling knives or slicing equipment, or danger from handling corrosive materials, such as cleaning chemicals or solvents, acids, alkalis, scale inhibitors, bactericides.
